HANGER FOR CONDUCTOR-WIRES.

To all whom it may concern s v Be it known that I, JOHN T. MORGAN, a citizen of the United States, residing at Charleston, in the county ofKanawha and State of West Virginia, have inventednew and useful Improvements in 'I-Iangers for I Conductor-Wires, of which the following is a specification.

This invention is an improvement in. de-

vices of the type commonly employed forthe suspension of trolley wires and other.

similar conductors.

One of the objects of the invention is to\.

provide a combined hanger and clamp so arranged that the conductor may be supported without placing the insulating body under tension, :but will be under compression alone. A further object is to provide a combined hanger and clamp composed of few parts which may be quickly and easily assembled,

or separated 'asdesired, for the purpose of' making repairs, substituting new parts and the like.. Ayfurtherobject isto provide a structed that the hanger may be readily alined with the wire. A. further object is to provide 1 a device of the type referred to, constructed to 1 reduce the chances of short circuiting, having means by which all of the paths of'possible short circuit are separated.

The-invention will be hereinafter fully set claims. v

In the accompanying drawing Figure l is a side elevation of a hanger constructed in accordance, with the'inven- 3 is a transverse section on the line 33, Fig. 2. Fig. 4: is a detail view illustrating the swivel support. Fig. 5 is a sectional view illustrating a slight modification.

. Referring tothe drawing, 10 designates a body of insulating material, preferably porcelain, provided with chambers 11', lo cated contiguous to opposite faces of the insulating body, said chambers being open at the bottom and also at their outer sides. The upper ends of the chambers 11 are connected by a channel 12, the portion of the insulating body surrounded by said cham-- bers and said channel, forming a supporting or suspension core 13. Extending transversely through the core 13, and passing between the chambers 11, is an opening '14, which registers with grooves 15, formed in the sides and top of the body 10.

Specification of Letters Patent. Patented Dec. 23, 1919.

' 1 v Application filed June 6, 1917. Serial No. 173,094.

The supporting member of the hanger 4 consists of a metal band or casting 16, passed through the opening 14, and shaped so as to lie within the grooves 15, the free ends of sa d band overlapping and being united by suitable means, as illustrated in Fig. 4. A

rivet-17 is passed through the band 16 and the solid bottom of a nut 18, designed to engage a threaded supporting stud, theconnectlon between the nut and the band 16',

branch 20, and a clamp portion 21, the angular portions 20 extending into the channel 12, the mam portions of said arms being suspended within the chambers 11, with the clamp portions extending below the core 13.

The conductor wire 22 is clamped between the clamp portions 21, the necessary pressure being maintained by means of a bolt and 1 nut 23, as illustrated in Fig. 3.

In practice, the band 16 is secured in positionby being passed through the opening 14, and bent around the insulating body,

from the drawing that when the clamping portions 21, are drawn together, the arms 19 are caused to rock sli htly on the core 13, until the angular branc cs 20 bear against the top of the channel 12, and in this manner said arms are locked against displacement. The arms 19 possess suificient resilienceto permit of the clamping action of the nut and .bolt '23, and the swiveled connection with the nut 18 permits the block 10, and the parts secured thereto, to be turned into a position to properly aline with the wire 22.

In Fig. 5 is illustrated a slight modifica- I 105 tion in which a single strap' or band 25 is employed as the suspension means, in lieu of the arms 19. In this form of the invention the ends 26, of the band are brought together, and clamp members 27, secured thereto by means of a bolt and nut, 28, by means of which arrangement the bolt and nut serve'thedouble function of securing the after which the ends of the bands are ata but never under tension, which is an important advantage in the art to Which the invention appertains. The relative arrangement of the supportlng device and the suspension device is such that all paths of possible short circuit are separated, and said members are of such simple construction that they may be readily assembled or separated, as maybe desired.

In practice, should the roof which supports the screw engaged by nut 18 to sustain the device, be inclined, as is not uncommon, the band 16 may be slipped around the body 10, and the arms 19 may be correspondingly shifted to compensate for the inclination and to suspend the conductor 22 in a central position.

Having thus explained the nature of the invention, and described anoperative manner of constructing and using the same, al though without of the forms in which it may be made, or all of the forms of its use, what is claimed 1s 1. A combined hanger and clamp of the character described comprising a body of attempting to set forth all .aaaeee insulating material provided with chambers separated by an insulating wall and open at the bottom, said body also having a diametricallydisposed channel connecting said chambers at the top through said insulating wall, a supporting band passed through the insulating wall between the chambers and below the channel, and at an angle to the latter, said band being passed over said insulating wall, a swiveled support for the band, and cated in said chambers and extending into said channel. v

2. A combined hanger and clamp of the character described comprising a body of insulating material provided with chambers separated by an insulating wall and open at the bottom, said body also having a diametrically disposed channel connecting said chambers at the top through said insulating wall, a supporting band passed through the insulating wall between the chambers and below the channel, and at an. angle to the latter, said band being passed over said insulating wall, a threaded attaching member," a swivel passed through said band and connecting the same With said attaching member, and conductor suspension means located in said chambers and extend ing into said channel.

In testimony whereof I have hereunto set JOHN T. MORGAN.
